Question about time lapse...

[Rylan Zolinski]

I've never shot a time lapse before but I want to try it out. I watched a few videos of some amazing footage and one of them says that they had 30 second exposure with 2 second intervals between shots. How is this possible?

If you are shooting in reeeeeally low light, or no light at all, you need that long for the shot to show up, the light is basically adding up over that duration.

morox,

I use a photix timer remote on my canon 5d/7d and its pretty straightforward.
In manual mode on the camera, the shutter time I set on the camera, and I only set 2 parameters on the remote, the start delay, and the interval. So say I set 2 seconds interval on the remote and 30 seconds on the cam.
When I hit start, the camera exposes at 30 and the remote simply "waits" for it to finish, counts 2 seconds before triggering the next 30 second exposure and so on..

I know it was quite confusing for me as well, but I just tried it now, I can say for other remote devices though only for what I have.

One might think that a longer exposure than the interval time will overlap, this must be what you mean?

Hope that helps.

Usually because they'll use a DSLR with a remote with the button latched in and the exposure set to 30 seconds. The camera takes about two seconds to save the previous photo (assuming long exposure noise reduction is switched off) and will then take another exposure. You probably have to turn continuous drive mode on as well.

People use this technique to take stacked star photos which are then combined into a single image in post processing.

This answered my question. I was using the EOS utility and the 5 second interval overlaps the 30 second exposure and so I was wondering how people were doing this correctly. I think purchasing a timer remote is my only option to fix this.
